Battery Replacement Blower for Sthil Gas BR-600 Leaf Blower ?

My Sthil BR-600 has been excellent; for several years; easy start & reliable.
677 CFM at 238 MPH & 64.8cc engine.

I use it primarily for fall leaves, excessive grass clippings, & small stick clean-up, etc.

I think you need VELOCITY to pick up material (especially if wet), then you need VOLUME to move the material.
It has started getting hard to start. It will run if I play w/ the choke & get it thoroughly warmed up.

Unfortunately, my local mechanic has quit working on all 2-cyl equipment. (too finicky ?)

His short recommendation: Buy a high-performance battery leaf blower. “You will never have a problem ! ! !”

What are battery powered, back-pack blowers, w/ similar or better specs, & at least 1 hour at full power?
 
I don't know the current state of things, but I'm thinking that an hour of continuous runtime at full power is gonna be a real tall order. Not impossible, but a huge, heavy backpack battery would be involved and that sounds super expensive. I haven't shopped those products ever, so I am just jabberin'
 
Battery can produce decent velocity, but not the volume. The top battery backpacks put out maybe 500 CFM, while the best gas blowers will do double that. And 20 N vs 40 N of force. It's not even close.

Similar to big saws, there may come a day when battery tech will catch up, but for now there's no replacement for displacement.
 
I love battery tools and use them whenever I get a chance. Haven't carried my gas handleld blower in the truck since buying the Husky battery blower over a year ago. That said, high CFM blowers seem to take a LOT of power and.... maybe... the new versions are finally up to the task? All the major manufacturers have a battery backpack model now or have one on the way, but I don't know anything about their real world performance.

I just saw there is a Milwaukee M18 one as well, but the specs seem pretty darn weak and this price doesn't include $400-$800 in 12ah batteries or any chargers. I've got a lot of M18 tools but am very much not impressed with the chainsaw or handheld blower, they are absolutely not pro quality or performance.

I'm seeing two different design philosophies with the 'large battery stuff', that being using one giant proprietary battery, or multiple smaller batteries. Multiple smaller battery systems only make sense to me if you already have that battery system and chargers. Otherwise your running a blower that uses 2-4 batteries at once and having to buy multiple chargers to recharge it in a reasonable timeframe, or just having to charge multiple batteries one at a time which would be terribly slow.
 
I'm reaching the same wear out on my BR600. For the cost of parts labour and time even mine it may be time to bite the bullet because there's a whole lot of great service from a fresh unit. Mine has multiple pull required syndrome but still always eventually fires up. Occasional decomp malfunction too. Could change the cam and crank seals but parts $$ and pita. Also beware of rod (piston) bearing knock.

power x time = big battery = $$ risk if malfunction, worse than BR600 woes IMO
 
I don't know that I've ever had to meaningfully work on a backpack blower.

I bought another BR800 last month to go with the 800 we normally use. I may still have the previous 600.

I have a lot of Milwaukee tools and batteries. Electric isn't the way for blowers, that I've seen. I wish Stihl would make a BR1200 or whatever number; a monster blower that can lift sod if it's not used properly.

Whether TruFuel or just ethanol free with a good quality oil...

I recommend TruFuel for folks that don't go through a lot of fuel - or when multiple people have to fill it. Have a friend that works with Team Rubicon and they only use premix because it saves them from people doing the wrong thing with fuel.

I don't lend my chainsaws to neighbors.

However, I have lent my leaf blowers, but I ALWAYS give them some of my gas for refill(s).

Check out the Taryl BR600 fix video for a preview should you get ambitious to work on it yourself. IIRC shows valve lash too.

Isn't Redmax current big cc's king of the hill? Never seen a real one yet,

Anyone used a RedMax EBZ9000-RH ?
Click to expand...
RedMax is a Japanese manufacturer owned by Husqvarna in 2007; USA headquarters in Charlotte, NC.
The RedMax EBZ9000-RH backpack blower reportedly:

Blow force: 56 N
Air speed (round nozzle) 216 mph
Air volume: 1245 CFM
91.3 fl. oz. fuel tank (up to 25% longer run-time vs competition)
weighs 26.5 lbs
79.4 cc engine delivers 5.5 hp
$800 MSRP

This thing sound like a beast; “too good to be true ?”.
Reliability; Service ? ? ?

BR600 65 cc engine vs redmax 79 cc engine. 15 more cc is about 25% more power but airflow behaves with a square law so say sqrt(1.25) = about 12% more velocity or flow depending how they're balanced off against each other. BR800 more volume less mph than BR600 w same engine. So I'm saying expect about 10% more performance than BR600.

Check lawn forums for reliability - but nearby servicing dealer most important IMO parts warranty etc


My BR600 has decided it doesn't like to restart hot. Restarts fine after cooling. Anyone, guesses? pita


edit - stealth autocorrect "reedman"!:)
